So i just started out with Arduino and need a little help from the guys experienced in this field.

I wanna know how to read the value of the resistor and display the value on an lcd screen. I know that the resistors have color codes on them, but i was just wondering if this was possible.
 


Its possible. You basically want to read the value of the resistor like an ohmmetrer and then take the output and display it. You want to build a multimeter of sorts using an Arduino.

Complexity level is pretty high, you will need to build a circuit using a multimeter IC and interface it with the Arduino via the Two Wire Interface (I2C) or the Serial Peripherial Interface (SPI) to read the resistor as input, and then drive the output through an LCD display or you can do it the hard way and build a circuit using a wheatstone bridge.

Once you have that part sorted out, then you will need to code the algorithm and include the needed libraries. The base code is not highly complex but its not exactly simple either.

I'd recommend starting with something simple like manipulating LEDs and turning stuff on an off with momentary open or close contact switches and maybe some npn + pnp transistors first and go from there.
 
I started a little earlier than you :) I have most of them ;)

If you need to bounce some ideas / designs / sketches, just give me a holler :)
 
bump for my Arduino friends!

just saw this. µSpeech by arjo129

uSpeech library
The uSpeech library provides an interface for voice recognition using the Arduino. Don't expect too much from it but you can create a very simple 10 word recognizer from this library. Feel free to fork it.

Minimum Requirements
The library is quite intensive on the processor. Each sample collection takes about 3.2 milliseconds so pay close attention to the time. The library has been tested on the Arduino Uno (ATMega32). Each signal object uses up 160bytes. No real time scheduler should be used with this.
